Weather in December
Temperature
December's advent notes a subtle adjustment in average high-temperature to a still warm 28.2°C (82.8°F) from November. In December, the temperature registers a significant dip to an average of 14.7°C (58.5°F) at night.Heat index
December's mean heat index is calculated to be 28°C (82.4°F). Constant exposure and activity lead to possible fatigue. Prolonged exercise may result in heat cramps.Note that heat index values are valued for light wind and location in the shade. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', represents the fusion of temperature and moisture in the air to suggest how warm it feels. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
